Apparently, Asin Thottumkal is more believable as Mithun Chakraborty’s sister than Nargis Fakhri. Or at least that’s the reason being given for why Nargis is out of ‘Khiladi 786′ and Asin is in. It is not clear if this is the only reason for the substitution. It had been reported that Nargis has signed a three-film deal with Akshay Kumar’s production house and ‘Khiladi 786′ was to be the first of these three films. Hopefully, the deal will not fall through, although the khiladi will be romancing Asin in this film, which he is co-producing with Himmesh Reshammiya. Shooting on the film began on June 2.
